a) the token is redeemable, and in that case why buy securities you don't intended to use (speculation is the only reason) b) or the company folds before delivering and the token is worthless, so by selling it you are just pushing the loss to a greater fool
Either way, this is objectively worse than Kickstarter.
People who buy diamonds, physical diamonds, may be speculating on them. Others may actually like the diamond. For whatever reason, they bought the diamond, and now own it, and can resell it. It isn't illegal to buy something in the hope it goes up in value. People do that all the time with videogames, cars, whatever.
Now, let's say ownership of a diamond was moved to the the blockchain. Not only could you buy and transfer it easily, provably, securely - you could even buy 0.000000001 diamonds, or 100000 diamonds, just as easily.
In my opinion, all of this is objectively better than kickstarter.
Sure, because you don't even have the little bit of oversight that kickstarter offers. In your case you can just keep pumping coins into the market while they have any meaningful amount of value. Then when they are worthless you just claim your project failed and take the money from selling the coins.
And what justifies these tokens you are offering having such a variable price? They aren't tied to the company equity or actual success of the company, but for your inability to launch when they would become completely valueless, in fact you claim they are a utility transferable for data but why would the price of the product/data being offered fluctuate other than speculation of a blockchain based crypto coin separate having nothing to so with the alleged utility.
The same reason the price of anything fluctuates. Do you think the price of mobile data should be different?
You can claim it's the same reason anything fluctuates, but point me to other products/goods/services with prelaunch fluctuating pricing.
If mobile data becomes more of a commodity, it, too, will have a free-floating price.
